ERR_SSL_VERSION_OR_CIPHER_MISMATCH on YouTube

freezey — Tue, 10 May 2022 09:02:22 GMT

My issue seems very similar to this one. When I try to open YouTube in Chrome on my WIndow 10 copmuter I get the following error:

------------------------------------------------------------------------------------------------------------------------------------

This site can’t provide a secure connection

www.youtube.com uses an unsupported protocol.

Unsupported protocol

The client and server don't support a common SSL protocol version or cipher suite.

------------------------------------------------------------------------------------------------------------------------------------

I've tried:

Clearing the browser cache and cookies
Checking for Windows updates
Using a different browser (FireFox. Same error)
Using a different computer (Win10 Laptop with Chrome. Same error)
Connecting over WiFi and wired to the router.

Since yesterday afternoon I am also facing the same issue. My mobile phone connecting through wi-fi do not face the issue.

I have tried rebooting... as it is only this combination (chrome, firefox on wi-fi) google search views this as an issue on the server side.

===============================

Secure Connection Failed

Thanks for reminding me.

This issue start yesterday (9th May 2022) in the afternoon.

I've now also tried:

Connecting using a Linux Virtual machine running on the Window 10 host. Same error in a FireFox browser.
Connecting using my mobile phone. This seems to work but I'm not sure if that's because it's automatically switching to the mobile phone ISP.

The webpage at .........might be temporarily down or it may have moved permanently to a new web address.

Do you have safeguard switched on?

I've now also tried:

Using my mobile phone as a wifi hotspot and connected my laptop to it. YouTube works.

All of the investigation is suggesting the issue resides with Plusnet or my Plusnet router.

Yes. I don't have a TV license so I use safeguard to blocked all the BBC domains.

Is that the root cause of the issue?

I'll trying turning it off and rebooting the router. I'll have to wait until lunch because I'm in a meeting.

I can access Youtube OK through Plusnet mobile, but for some reason
conservativewoman.co.uk
website has been blocked. Is there something strange going on?

Re: ERR_SSL_VERSION_OR_CIPHER_MISMATCH on YouTube

freezey — Tue, 10 May 2022 11:03:40 GMT

That did it!

I forgot that safeguard is managed through the website and not the router so it didn't require a reboot.

Thanks dvorak

It's odd, I wonder if YouTube has been added to some category overnight.

Raised an escalation to ask staff to have a look.

Have not changed anything, what is safeguard and why would it suddenly switch itself on?

Running on Chrome and Win7 Home Premium on laptop, however as this is also affecting firestick, Win8 and Chrome, Samsung smartphone, I do not think this can be related to operating systems surely?

Safeguard is a plusnet product for online 'protection' https://www.plus.net/broadband/extras/online-security/
You can see if it is activated here SafeGuard | Plusnet

Thanks for raising it with plusnet. Your fix works but it's a work around to the problem. The root cause resides in Safeguard and I'd still like to use it, rather than having to choose between Safeguard or YouTube.

Thank you Deb,

That certainly worked, although not an ideal solution so it looks like a Plusnet/Safeguard issue.

Safeguard/Youtube

Hello,

Late yesterday afternoon(9/5/2022) I was unable to access Youtube via my Smart TV, Windows 10 Laptop Or Ipad. I thought it was an issue with Youtube so left it overnight.

Having tried again this morning(10/5/2022) I have had the same problem. So, the issue seemed to point to something going on with Plusnet.

I noticed in my account that Safeguard was switched on. I presume this must have been set to on since I have had Plusnet Broadband. In terms of amending any of the settings, I haven't adjusted any of them. But, by setting Safeguard to Off I am now able to access Youtube.

That suggests that either Safeguard has been updated/changed or something within Youtube has changed which had affected Safeguard.

If anybody has any thoughts to offer then I would be interested to hear them. thank you.

Gary
